将包含符号操作的NSString转换为NSURL

Question

我想将包含签名操作的NSString转换为NSURL：

NSString *urls = @"https//graph.facebook.com/fql?q=select+actor_id,created_time+from+straem+where+created_time+>+2661222&access_token";
NSURL *realurl = [NSURL URLWithString:urls];

realurl return - ＆gt;＆gt;零

主要问题是created_time+>+2661222，实际上＆＃34; ＆gt; ＆＃34;签署操作。  NSURL无法转换它。

Answer 1

听起来您可能想要使用NSString's "stringByAddingPercentEscapesUsingEncoding:" method。

换句话说，比如：

NSString * urls = @"https://graph.facebook.com/fql?q=select+actor_id,created_time+from+straem+where+created_time+>+2661222&access_token";
NSURL * realURL = [NSURL URLWithString: [urls stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]];

Answer 2

首先尝试转义字符串：

NSURL *realURL = [NSURL URLWithString: [urls stringByAddingPercentEscapeUsingEncoding: NSUTF8StringEncoding]];
